Implementation of a Multi-Channel UART Controller Based on FIFO Technique and FPGA

摘要：

To meet modern complex control systems communication demands, the paper presents a multi-channel UART controller based on FIFO(First In First Out) technique and FPGA(Field Programmable Gate Array). The paper presents design method of asynchronous FIFO and structure of the controller. This controller is designed with FIFO circuit block and UART (Universal Asynchronous Receiver Transmitter) circuit block within FPGA to implement communication in modern complex control systems quickly and effectively. Form the communication sequence diagrams, it is easily to know that this controller can be used to implement communication when master equipment and slaver equipment are set at different Baud Rate. It also can be used to reduce synchronization error between sub-systems in a system with several sub-systems. The controller is reconfigurable and scalable.
